If you have a profile advertisement and you want to disallow visitors from opening your ad you can easily add that region to your blocklist.
You just have to give a tick for the selected country on the list at privacy tab on the profile editor form.
Although it's not an official feature but it works at least a 99.5% accuracy. Note that in profile listing your profile is still visible but visitors from the blocked country/countries can not open it.
